Why bother to design lenses for cameras with prisms and mirrors when almost everyone is content with an OLED display? Virtually every lens ever made can be adapted to the NEX (albeit with manual focus and aperture). And some clever adapter maker will probably solve those issues pretty soon.....

I agree but OP was asking about FF and right now FF means A mount.FF Nex is a rumor (for now).This should give OP something to think about in terms of FF A mount future (I know, I know )
